In this thrilling novella set after the events of "Fracture the Spider's Web," darker things lurk outside the city. Before Ave and Elliot met the three siblings in a series of events that would change everything, they operated a superhuman detective business. Finally, with the first break they've had since the train wreck began, Ave and Elliot have a chance to take on new cases, and someone wants to join them. The newest mission tells of strange grinding noises and disappearing machine parts during the dark October nights of the sparsely populated oil country in rural Pennsylvania. A promise of good fun. But, as Yuuhi says, there has never been a case that has gone as expected, and there's never been a case that has ended well. Set a month after the collapse of the overpasses, "Interlude" shows the unwinding of events through the eyes of other characters and boasts the usual quirks and laughs of the cast - plus a twist of horror.
